MMC: add weak function to detect MMC/SD card
Most controllers can check if there is a card in the slot. However, they require pins that could be not available because required by other functions and the detection of a card must be performed in another way. This patch adds a weak function that a board can implement to add its internal custom way to check the presence of a MMC/SD card. Signed-off-by: Stefano Babic <sbabic@denx.de>
